Kea DC to 400 MHz NMR Spectrometer


The Kea2 400 MHz NMR Spectrometer

Powerful, but still compact and portable, Magritek’s new generation of Kea NMR spectrometer, the Kea2,  significantly improves performance and extends the frequency range of our signature NMR spectrometer line.

With a footprint of 36 cm x 23 cm (12″ x 8″) by only 15 cm (5″) high, the Kea2 conserves lab space. Weighing less than 5 kg (11 lbs), it is easily moved and operated in almost any environment.


  • Compact and lightweight
  • Models from DC to 400 MHz
  • Optional second transmit channel
  • Optional high stability oven controlled oscillator
  • Optional four channel imaging module
  • External input trigger
  • Can operate off a 24 V battery


The extended operating range and features of the Kea2 series makes it useful for a wide range of applications:

  • Spectroscopy, time domain relaxation and imaging
  • Mobile permanent magnets
  • High frequency superconducting magnets
  • Ultra-low frequency systems (e.g. Earth’s Field)
  • Single-sided NMR

Modular and Flexible

The modular Kea2 spectrometer is customised to meet your requirements. Existing systems are easily integrated with Kea2′s optional internal RF amplifier, preamp and duplexer modules. Kea2′s imaging module provides control of up to 4 gradients.

Direct digital transmit and detect

Kea2 uses no intermediate mixing frequencies — meaning no quadrature issues. Kea2′s 1 GHz digital transmit circuit performs direct waveform synthesis at up to 400 MHz. The receive module directly digitises the NMR signal at 100 MHz for a high quality, low noise NMR signal. This is the same technology used in most modern high field NMR spectrometers but is available with Kea for a fraction of the price.


The lightweight, low-footprint Kea2 spectrometer is convenient to use in almost any environment. Powered by two standard 12 V car batteries, the Kea2 can be operated far afield in any remote location.
